Product feature of silicone grease for o rings

SATOP® 8425 Thermal conductive silicone grease is used in thermal conductive materials in electronic devices, and has excellent thermal conductivity. This product with low viscosity, Can make the cooling surface of the electronic components and close contact between the radiator and reduce the thermal resistance, It can effectively reduce the temperature of the electronic components, extend the service life of electronic components and improve reliability. SATOP®8425 thermal conductivity silicone grease will not be cross linked, in the process of electronic assembly, easy operation if has any change or replacement of the radiator.

In addition to high thermal conductivity, no stress when used. High stability under – 50 to + 200 ℃, and has excellent weather resistance, radiation resistance and excellent dielectric properties.

SATOP® 8425 is widely used in LED, microprocessor, a memory module, high-speed buffer memory, sealed integration chip, DC/DC converters, IGBTS and other power module, power semiconductor, solid state relay and bridge rectifiers and other fields.silicone grease for o rings is best.
